The Jaguars (3-2) signed veteran Jamaal Charles on Tuesday with the expectation that Fournette would be sidelined for an extended period. They also placed third-stringer Corey Grant (foot) on injured reserve.

No one would be surprised to see Fournette sidelined until after Jacksonville's bye week, potentially returning Nov. 11 against Indianapolis.

The second-year pro from LSU already has missed six of 21 regular-season games and left his only two starts this season because of hamstring tightness.

He has 71 yards rushing on 20 carries this season.
